You create a bolt of lightning that arcs toward a target of your choice that you can see within range
. Three bolts then leap from that target
to as many as three other targets, each of which must be within 30 feet of the first target. A target can be a creature or an object and can be targeted by only one of the bolts.
A target must make a Dexterity saving throw
. The target takes 10d8 lightning damage
on a failed save, or half as much on a successful one.
At Higher Levels: When you cast
this spell using a spell slot
of 7th level or higher, one additional bolt leaps from the first target to another target for each slot level above 6th.
